1. A self-sealing cuff, comprising:
base material defining a first end, a second end, and having a “C” shaped cross-section defining opposing edges extending between the first and second ends; and
first and second reinforcement members embedded within the base material, the first reinforcement member extending axially along a first length and including elements that extend at least partially around a circumference of the base material, the second reinforcement member extending axially along the first length and including elements that extend at least partially around the circumference of the base material, the second reinforcement member spaced apart radially from the first reinforcement member,
wherein the first and second reinforcement members comprise first and second zigzag members that extends axially along the first length and include alternating loops defining peaks and valleys connected by arc elements that extend at least partially around the circumference of the “C” shaped cross-section, the second zigzag member is positioned concentrically around the first zigzag member, and
wherein the first and second zigzag members are out of phase with one another such that peaks of the first zigzag member are disposed opposite valleys of the second zigzag member along the opposite side edges and the arc elements of the second zigzag member overlap the arc elements of the first zigzag member at overlap points.
